  • Page 7: Cautions For Safety In Use

    ・Cautions for Safety in Use Danger Applications (1) This pump is not designed to be explosion-proof, and should therefore not be used to discharge explosive gases. (2) In addition to discharge of gas via the outlet, gas may also leak from other parts of the pump, and it should therefore not be used with toxic gases.
  • Page 8 Warning Operation (14) This pump is not designed to be explosion-proof. When using the pump, ensure that there are no inflammable materials such as solvents, or explosive gases, in the vicinity. Use under such conditions may result in injury or fire. (15) Inserting fingers or objects into the motor inlet may result in electric shock, injury, or fire.
  • Page 9 Caution Operation (4) Touching rotating components (eg motor, main shaft, axial joints, cooling fan) while the pump is in operation may result in injury. (5) The overload protector operates when the pump becomes excessively hot. Touching it in this condition may result in burns. (6) Touching the motor while the pump is in operation or while it is still hot immediately after having been switched off may result in burns.
  • Page 10 Note Installation (1) The pump may malfunction if it is subjected to shocks or tipped over on its side. Applications (2) This pump is not designed to be corrosion-proof. Use it only with clean air at normal temperature, or with gases of equivalent characteristics. (3) This pump is designed solely for vacuum extraction.
